Hmmm, my Amiga 1000 cost $1200 with 512k and an extra drive, now I could use the new A500 but figures are shaky on it so lets continue. A Cray will run you a minimum greater than $120,000, that's 100 Amigas with an *extremely* conservative estimate on the cost of Crays. What Apollo did with 22 days (or was it 23?) of Apollo cpu on ~100 Apollos. I presume that we will consider the staff to maintain both setups to be of equivalent cost favoring the Amiga staff on being able to still afford beer and chinese food. -- Jim Hutchison UUCP: {dcdwest,ucbvax}!sdcsvax!hutch ARPA: Hutch@sdcsvax.ucsd.edu 2049 6d61 7320 6c65 2066 6572 7270 7365 6e65 6974 676e 6920 206e 6874 7369 6120 7472 6369 656c 202c 2049 6572 7270 7365 6e65 2074 6e6f 796c 6d20 7379 6c65 2e66
